I'm not sure exactly where to post this, but I'll try here...
I'm running Ubuntu 17.10. I recently found that the HuC nor GuC were not loaded by default despite the firmware being present. I guess I thought this was something that was done automatically with newer kernels. But even after making the necessary changes to load the HuC and GuC, the HuC loads fine, but the GuC is failing.
I add the following kernel boot parameters:
I successfully ran:
update-initramfs -u -k all
I then rebooted and checked again.
Hello Night, could you try forcing the i915 options at your grub command line? Something like "i915.enable_guc_loading=2 i915.enable_guc_submission=2"
I actually tried the value of 2 before trying the value of 1, and my system failed to boot graphically. I was forced to edit the grub values via terminal to get back to a graphically bootable state.
I will try again, and this time I will see if I can note dmesg errors.
Couldn't get to dmesg directly during the trial boot as it won't allow terminal access, but here's what I could grab from /var/log/syslog:
I can confirm, I experience exactly the same issues.!!!
And i have also a lot of tearing with my system's graphics (Wayland or Xorg, same issues)
I am on HD 620 (Lenovo T470s)
My logs also look the same!
Some things to add:
I had more information I tried adding here earlier, and the site tried to flag me as a spammer. So, I decided to post it elsewhere: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1728238
There does not appear to be a way to limit post notification emails in my site profile settings, and ironcially I am the one getting flooded with hourly spam claiming there have been new posts on this topic when there have been no new posts. The only option is to completely unsubscribe, but then I would receive nothing. This is not ideal.
The information I was going to post boiled down to it being an initramfs-tools issue due to the version Ubuntu 17.10 is running and the fact that there was an upstream issue with initramfs-tools in Debian which is now fixed.
There's an option on the profile to change how often you want to receive updates. Does this work for you?
The steps to change the frequency are:
